Selective Laser Sintering (LS)

Laser sintering is a generative layering process and belongs to rapid prototyping. The workpiece is thus built up in layers.

Thus, by the action of the laser beams arbitrary three-dimensional geometries can be generated with undercuts also, which cannot be produced by a conventional casting manufacturing.
